Swivel Joints Technology Explained

Swivel Joints are key components for the transportation of liquids and gases for a wide range of industries

Swivel Joints – Basic Working Principles

Whether you work in the chemical, petrochemical, or oil and gas industries, among others, swivel joints are key components. They guarantee smooth transportation of liquids and gases between fixed piping and movable equipment.

Swivel joints also play an essential role in hose reels, piping systems, wastewater treatment, just to name a few. Their use in loading arms provides flexibility, easy handling and maximum safety for operators.

It also sustains optimal performance under high internal pressures, traction and bending forces.

The first step while choosing swivel joints is to deeply understand the specific parameters of an application. Depending on the application, swivel joints are available in various combinations of sizes, seals, connections. They are manufactured out of various metals, including carbon steel, stainless steel, or aluminum, to ensure pressure, temperature, and corrosion resistance.
When struggling to find the perfect solution for your industry, our experienced engineers at Emco Wheaton are here to help you. They can determine the appropriate swivel joint design for your application and even help you customize a swivel joint for you.
